I belong to a club in BR. As far as what's up that way, I have no idea. I know there is a supply store in TC, and I would expect them to know of a club in that area.
I think a casual club could be created pretty easily. We took our time and set up bylaws and policies as a matter of course so that we can prepare for situations that might arise down the road. If it were just a club for hanging out, brewing and talking about beer, you probably don't need to do that much work. We are planning on being an educational club focused on making people aware of the hobby, doing experiments, and hosting community events while also having a good time.
Last night at our monthly meeting we held a club competition for American Pale Ales, and this Saturday we are hosting a Learn to Brew Day (in conjunction with the AHA event in November) at a nearby brewery to show people the various aspects of the hobby.
